Thing to write about street eatery (6)
I believe the answer is:
bistro
'eatery' is the definition.
(I've seen this before)
'thing to write about street' is the wordplay.
I cannot really understand how this works, but
'street' could be 'st' (abbreviation) and 'st' is found in the answer.
The remaining letters 'biro' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for bistro that I've seen before include "family concern perhaps" , "somewhere to eat" , "Small inexpensive eatery" , "Small French bar and restaurant" , "'Small, inexpensive restaurant (6)'" .)
